When I arrived, all three fledglings were on the nest railing sitting side by side. Then one took off for a building on 95th Street. It landed a floor below the mother, and it took a bit of time for it to figure out it could use the stairs.
I thought wow, how smart of the mother to bring food there. She's teaching the fledgling where the next meals will be and bringing the fledgling to a quieter location. But in watching my video, it might have been just that the mother was feeding herself on the building and the fledgling came in and stole the meal. At some point in the middle of the fledgling eating, the mother tried to get the pigeon back. I'll never know which scenario was right, but it shows how easily you can get the story wrong.
In addition to the issues with the meal, the persistent and annoying American Kestrel was causing trouble and if you watch the video a house sparrow couple were a bit worried as they had a nest under where the eating took place.
